Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a pneumatically controlled air cut-off anti-falling protection mechanism. Background Art

[0002] With the continuous development of industrial technology, improving equipment safety is one of the factors we give priority to in technology research and development. For example, when selecting a pneumatically controlled cylinder, its working principle is to use the air pressure provided by the air source to push the piston inside the cylinder body outwards, so that the rod part outside the cylinder can achieve thrust or push the load in the required direction.

[0003] After a large amount of retrieval, it is found that the Chinese patent publication number is CN212429397U, which discloses a cylinder with a self-locking function and belongs to the technical field of telescopic cylinders. The cylinder with a self-locking function includes a cylinder body, a rear cover, a front cover, a piston rod, a piston, a lock sleeve and a self-locking device; the rear cover and the front cover are respectively fixedly connected to both ends of the cylinder body; one end of the piston rod is fixedly connected to the piston, and the other end passes through the front cover; the piston rod moves back and forth in the cylinder body under the drive of the piston; the lock sleeve is fixedly connected to the bottom surface of the piston, and the self-locking device vertically passes through the cylinder body and the rear cover, and the movement of the lock sleeve can be restricted through the self-locking device, so as to restrict the movement of the piston and the piston rod. This cylinder with a self-locking function locks the cylinder piston through a mechanical structure, which is safe and reliable compared with the traditional way of maintaining a stable jacking force of the cylinder, has a simple structure and a wide application range, and has low requirements for the air source and air circuit components.

[0004] When the air source supply is insufficient or the air source suddenly cuts off, the load cannot obtain the required thrust, which will cause serious safety hazards. If the existing self-locking cylinders are used, it will require a large amount of R & D and equipment investment costs.

[0005] In view of the above defects, the designer actively conducts research and innovation in order to create a pneumatically controlled air cut-off anti-falling protection mechanism, making it more valuable in industry. Summary of the Utility Model

[0030] Embodiment

[0031] As Figures 1 to 3 shown,

[0032] A pneumatically controlled air cut-off anti-fall protection mechanism, including a support 1 and a working unit 5. A driving structural member 2 is installed on the support 1. The driving end at the top of the driving structural member 2 is connected to the upper working unit 5 through a robotic arm 3, where the driving structural member 2 can be a cylinder or the like. A robotic arm limiting structure 4 is installed on the support 1 on the right side of the robotic arm 3, and the robotic arm limiting structure 4 is a limiting column connected by threads.

[0033] The working unit 5 includes a jacking cylinder 6, a connecting plate 12, and a workpiece 14. The jacking cylinder 6 is installed on the robotic arm 3. The driving end at the top of the jacking cylinder 6 is connected to the workpiece 14 on the right side through the connecting plate 12. A handle 13 is installed on the connecting plate 12, and at least one positioning pin 15 is installed on the workpiece 14.

[0034] I. Anti-fall protection mechanism:

[0035] A protection bracket 10 is installed on the robotic arm 3 at the rear side of the connecting plate 12. A protection magnet 11 is installed on the front side of the top of the protection bracket 10, and the protection magnet 11 can be magnetically attracted to the rear side of the connecting plate 12.

[0036] Among them, the protection magnet 11 is an electric protection magnet.

[0037] In addition, a connecting plate magnet with a magnetic polarity opposite to that of the above-mentioned protection magnet 11 is installed on the rear side of the connecting plate 12.

[0038] II. Limiting structure of the connecting plate 12 during the jacking process of the jacking cylinder 6:

[0039] At least one limiting bracket 7 is installed on the left side of the jacking cylinder 6. A lower limiting block 8 is installed on the top of the limiting bracket 7. An upper limiting block 9 adapted to the above-mentioned lower limiting block 8 is installed on the connecting plate 12 directly above the lower limiting block 8.

[0040] Among them, the top of the lower limiting block 8 is a conical protrusion, and the bottom of the upper limiting block 9 is a conical groove adapted to the above-mentioned conical protrusion.

[0041] Brief description of the working process of the present utility model:

[0042] In the state where the cylinder is not ventilated, the movable connecting plate 12 is in the initial state. As Figure 3 shown, the position of the connecting plate 12 at this time is 12a, and the position of the workpiece 14 at this time is 14a.

[0043] In the state where the cylinder is ventilated, the piston inside the cylinder body is pushed out by the air pressure. The piston pushes the movable connecting plate 12 to the open position. At this time, the protection magnet 11 just attracts the movable connecting plate 12 and the workpiece 14 connected to the movable connecting plate 12. As Figure 3As shown, the position of the connecting plate 12 at this time is 12b, and the position of the workpiece 14 at this time is 14b.

[0044] At this time, the pneumatic air cut-off anti-falling protection mechanism (i.e., the protection bracket 10 and the protection magnet 11) can play an auxiliary support effect. When the air source supply is insufficient or the air source suddenly cuts off, the movable connecting plate 12 and the connected movable part of the workpiece 14 will fall due to gravity, and the magnetic force of the pneumatic air cut-off anti-falling protection mechanism will act as the force to support the movable part of the tooling and keep it in the open state.

[0045] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
